Modules using the **N-type TOPCon** technology offer better performance and stability over time, even in demanding conditions, compared to many standard P-type solutions, resulting in more reliable energy production over the long term. The **double-glass** construction enhances resistance to environmental factors, and the **bifacial** design allows the panel to utilize reflected light from the ground - a real advantage on bright roofs, carports, and ground-mounted installations. A key feature is the use of **Cutting Free Technology**, which helps minimize microcracks and improves reliability during transport and operation. The overall design offers a sleek, all-black appearance, ideal for modern homes and commercial buildings where architectural design is important. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 222.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - At 23.5 kg, this panel is 1.5 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### How does N-type TOPCon cell technology in the Ulica Solar All Black 430-445 W series differ from standard P-type panels? N-type TOPCon cells use an additional tunnel oxide layer that reduces recombination losses and raises module efficiency above 22%. In practice this means a lower annual degradation rate than typical P-type PERC panels and better performance under high temperatures and low irradiance, resulting in higher, more stable energy yield throughout the system's lifetime. ### How much extra energy can I get from the bifacial design of this panel series? Bifacial panels in the All Black series also generate power from the rear side, capturing light reflected off the ground surface. Depending on mounting height and surface albedo (light-colored roofs, white gravel, concrete), the typical real-world energy gain ranges from a few to over ten percent compared to a monofacial module of the same rated power, with the biggest benefit seen on ground-mount or carport installations. ### What warranty comes with the Ulica Solar Double-glass Bifacial TOPCon All Black 430-445 W series? The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 30-year power performance warranty guaranteeing limited, linear power degradation over that period. These extended warranty terms exceed those of typical P-type panels, which is common for N-type TOPCon technology and adds significant long-term security to the investment. ### Does the double-glass construction in this series mean greater durability and higher panel weight? Yes, using glass on both sides instead of a standard rear backsheet improves resistance to moisture ingress, microcracking, and PID degradation, which is especially valuable in humid climates and bifacial installations. The trade-off is a somewhat heavier module compared to backsheet versions, so roof load capacity should be checked before installation, particularly on older roof structures. ### What is Cutting Free Technology in Ulica Solar panels and how does it improve reliability? Cutting Free Technology reduces the number of mechanical cell-cutting steps during manufacturing, lowering the risk of microcracks that often only become visible months after installation. This makes the panel more resilient to transport, mounting stresses, and thermal or mechanical loads over time, reducing the risk of power loss and failures during long-term operation. ### Is Ulica Solar a Tier 1 manufacturer, and is it a safe choice for a loan-financed installation? Ulica Solar is a Chinese manufacturer with over a decade in the industry, but it currently does not appear on the BloombergNEF Tier 1 list, which primarily ranks manufacturers by supply volume to large bankable projects rather than technical module quality. For residential and commercial installations financed through standard consumer loans this is generally not an obstacle, though it's worth checking a specific lender's requirements before applying. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ulica-solar-n-type-topcon-1722mm-430-445w-bifacial-all-black-770dc93b06de.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [Ulica Solar UL-395M-108HV](https://comparepv.com/panel/ulica-solar-ul-395m-108hv) | 395 W | Hotter, -2.1 pp, -5 yr warranty | | [Ulica Solar UL-400M-108HV](https://comparepv.com/panel/ulica-solar-ul-400m-108hv) | 400 W | Hotter, -1.8 pp, -5 yr warranty | | [Ulica Solar UL-405M-108HV](https://comparepv.com/panel/ulica-solar-ul-405m-108hv) | 405 W | Hotter, -1.5 pp, -5 yr warranty | | [Ulica Solar UL-430M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-430m-108adgn) | 430 W | -0.3 pp | | [Ulica Solar UL-440M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-440m-108adgn) | 440 W | +0.2 pp | | [Ulica Solar UL-445M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-445m-108adgn) | 445 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/ulica-solar-ul-435m-108adgn Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
